Texas Instruments PCI4410APDV

Overview

PCI4410APDV from Texas Instruments is a PCI-to-CardBus/PC Card bridge controller in 256-ball MicroStar BGA (1.0 mm pitch), supporting PCI Revision 2.2, CardBus (32-bit, 33 MHz), and 16-bit PC Card interfaces. It integrates distributed DMA, OHCI-Lynx IEEE 1394 link-layer support, ExCA-compliant socket control, and power management for suspend/resume, targeting notebook expansion and docking systems.

For engineers reviewing the PCI4410APDV datasheet, PCI4410APDV pinout, PCI4410APDV application, or PCI4410APDV equivalent, this device requires attention to PCI timing compliance (tSU/tH for FRAME#, IRDY#, TRDY#), CardBus voltage switching (3.3 V/5 V detection), ExCA register mapping, and OHCI CSR initialization sequence - all critical for reliable hot-plug and legacy I/O coexistence.

Technical Context

The PCI4410APDV implements dual-function PCI configuration space (Function 0: PCI-to-CardBus bridge; Function 1: OHCI 1394 controller), with separate memory-mapped and I/O-mapped ExCA register access. Its bridge logic handles address translation between PCI bus and CardBus/PC Card memory/I/O windows, including dynamic window sizing and prefetch enable.

It supports PCI power management D0–D3hot states, CardBus-specific PME signaling via RI_OUT and D3_STAT, and integrated SMI generation for system-level suspend coordination. The device includes on-die pullup resistors for PC Card interface signals and a programmable internal ring oscillator for low-power clocking during suspend.

Key Specifications

Pinout & Package

PCI4410APDV is housed in a 256-ball MicroStar BGA package (17 mm × 17 mm, 1.0 mm pitch), optimized for high-density notebook and docking station PCB layouts. Ball assignment follows TI's PDV terminal naming convention, with dedicated banks for PCI, CardBus, PC Card, IEEE 1394 PHY, zoomed-video, and power domains.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PCI-to-CardBus bridge applications.

Compared with PCI9054-AC, PCI4410APDV delivers integrated CardBus/ExCA functionality and OHCI 1394 in one die, reducing system-level complexity and validation effort. Against PCI4510PAG, it offers proven maturity and broader driver support but lacks extended temp rating and 1394b features - making it optimal for cost-sensitive consumer docking applications.

FAQ

What is the primary function of the PCI4410APDV?

The PCI4410APDV is a dual-function PCI-to-CardBus/PC Card bridge controller with integrated OHCI 1394 link-layer support. Its primary function is to enable PCI-based hosts (e.g., laptops, docking stations) to communicate with CardBus, 16-bit PC Card, and IEEE 1394 peripherals through a single, ExCA-compliant silicon solution - eliminating the need for discrete bridge chips and external FireWire controllers.

Does the PCI4410APDV support hot-plug insertion and removal of PC Cards?

Yes, the PCI4410APDV fully supports hot-plug operation via its ExCA-compliant socket registers and dedicated card-detect logic. It monitors CD1#/CD2# signals, generates Card Status Change interrupts, and updates the Socket Present State Register automatically. The device also coordinates power sequencing with external switches like the TPS2211 using D3_STAT and RI_OUT signals - all required for robust hot-plug behavior in Windows and Linux drivers.

What package type and ball pitch does the PCI4410APDV use?

The PCI4410APDV is packaged in a 256-ball MicroStar BGA with a 1.0 mm ball pitch and 17 mm × 17 mm body size. This package is RoHS-compliant and lead-free, designed for high-density PCB layouts typical in notebook and docking station applications. Ball assignments follow TI's PDV terminal naming scheme, grouped by functional domain (PCI, CardBus, PC Card, IEEE 1394, power).

How does the PCI4410APDV handle power management for suspend/resume operations?

The PCI4410APDV implements comprehensive power management per PCI D0–D3hot, CardBus suspend/resume, and ACPI 1.0 specifications. It asserts PME# on PCI, drives D3_STAT for external power switch control, and uses RI_OUT for wake events. Its internal ring oscillator maintains timing during suspend, and the Power Management Control/Status Register (PMCSR) allows software to program wake-enable bits and monitor power state transitions - all verified in TI's SCPS059 data manual.

Is the PCI4410APDV compatible with standard OHCI 1394 drivers?

Yes, the PCI4410APDV's Function 1 implements a fully compliant OHCI-Lynx controller with standard CSR architecture, isochronous context registers, and interrupt event/mask registers defined in the OHCI specification. It enumerates as a Class 0C00h (Serial Bus Controller) device with Subclass 00h (IEEE 1394) and supports all mandatory OHCI features - enabling out-of-box compatibility with Microsoft 1394bus.sys, Linux firewire-core, and third-party FireWire stack drivers without modification.
